Longitudinal relationships between COVID-19 preventative behaviors and perceived vulnerability to disease

Abstract

Engagement in infection-preventing behaviors (e.g., mask wearing) has become crucial in the context of the COVID-19 pandemic, and health-related anxiety may be an important determinant of individual compliance with recommended guidelines. However, little is known about transactional associations between health anxiety and preventative behaviors, particularly with respect to COVID-19. The present study aimed to longitudinally examine the links between preventative behaviors and both emotion-driven (Germ Aversion) and belief-based (Perceived Infectability) aspects of health anxiety during the COVID-19 pandemic. We hypothesized that greater health anxiety at Time 1 (early in the pandemic) would predict future compliance with preventative behaviors six months later. Two hundred and ninety-six adults (M/SDage= 30.9/10.9 years, 42.2% female) completed two online assessments during the COVID-19 pandemic (Time 1 =June 2020; Time 2 =December 2020). Longitudinal cross-lagged analyses revealed that initial Germ Aversion predicted greater engagement in preventative behaviors at follow-up (β = 0.16; p = <.001), over and above initial engagement in such behaviors. Similarly, initial engagement in preventative behaviors predicted increases in Germ Aversion at follow-up (β = .23; p = <.001), over and above initial Germ Aversion. The present findings indicate that affect-driven aspects of health anxiety have a complex transactional relationship with engagement in behaviors aimed at curbing the spread of the COVID-19 pandemic. Clinical and public health implications are discussed.
